How do I analyze the RAM/Disk Space requirements for scanned data from a generated report?

You can analyze the RAM/Disk Space requirements from a generated report.

Follow these steps:

1. Run ArcserveDeduplicationAssessment.exe from the downloaded folder or from the following UDP folder path if you are using Arcserve UDP:

   C:\Program Files\Arcserve\Unified Data Protection\Engine\BIN\Tools\RPS Planning

2. From the Scan Nodes screen, click Add Node and add all the source nodes.
3. From the Protected Nodes and Volumes section, select the nodes and volumes that you need to scan.
4. Click Scan Nodes to collect all the hash keys for selected nodes/volumes
5. From the Create Report tab, select the corresponding scan with nodes and volumes and click Create Report.

   Once the Report generation completes, the View Reports tab is displayed.

6. From the View Reports tab, click the Scanned Volume Charts section.

   By default the Disk and Memory Usage trend chart appears.

The following screenshot is an example of Scanned Volume Charts on Day one:

Select Disk and memory Usage Trend chart, to display data size trend for selected scan data for a particular deduplication block size.

The following screenshot represents the Disk and Memory Usage Trend chart for the first scan on Day one:

Note: On Day one, trend shows the data only for one scan.

In the Disk and Memory Usage Trend chart, 140.9 GB of raw data is scanned on Day one and the data written on disk with Maximum Compression is 42.4 GB. Data written on disk with Compression Disable is 71.4 GB and data written on disk with Maximum Compression is 34.7 GB. To protect this data, memory required is 0.715 GB and memory required when SSD is enabled is 0.03GB.
